Fix SpeculatorsConfig now that PreTrainedConfig is a dataclass in Transformers

[hmellor]

Since Transformers converted PretrainedConfig to a dataclass, users will see unexpected keyword argument errors on SpeculatorsConfig.__init__.

This PR adds a passthrough so that SpeculatorsConfig.__init__ can accept kwargs and passes them directly to PretrainedConfig.__init__ which also accepts kwargs

Code Review

This pull request aims to fix an issue with SpeculatorsConfig initialization when used with newer versions of transformers where PretrainedConfig is a dataclass. The proposed change introduces a passthrough __init__ method. However, the implementation might be incomplete, as it could propagate the original error to the superclass constructor call. I've left a comment with a detailed explanation of the potential issue and how it could be addressed.

This fix may be incomplete. If the unexpected keyword argument error is due to PretrainedConfig being a dataclass with a standard generated __init__, that __init__ won't accept arbitrary **kwargs. Consequently, this call to super().__init__(**kwargs) will likely fail with the same error. The keyword arguments should be filtered to pass only those that PretrainedConfig.__init__ accepts. This can be done by inspecting the parent's __init__ signature.

You're wrong, but the docstring didn't tell the whole story, I'll improve it.
